DFS4573E UNABLE TO CALL USER EXIT TYPE – tttttttt FUNCTION - ffffffff REASON - cccccccccccccccc RC - rr
Explanation
IMS was unable to call any exit routines of the specified user exit type.In the message text:
- tttttttt
- The user exit type.
- ffffffff
- The function code that was to be passed to the exit. If there is no function code, this part is blank.
- cccccccccccccccc
- The reason the exit type could not be called. Possible reasons
are:
- IMOD GETM ERROR
- An IMODULE GETMAIN error was encountered.
- NO DPST STORAGE
- The PSTDUXIB field that is supposed to point to the pre-allocated storage for the interface block and parameter list for dependent region PSTs (DPSTs) was 0. Return code rr is 8.
- rr
- The return code from the service that received an error. If the error does not have a return code, this field is blank.
System action
In most cases, the IMS system continues processing. However,
the IMS system might take additional actions to the IMSMON and the FASTMON exit type in the
following circumstances:- If the message is issued for IMSMON, IMS does not call the IMSMON exit type and continues processing regardless of the reported reason. This message is issued only once for the lifetime of the IMS system. If the storage shortage is eventually relieved, the calling of the IMSMON exit type resumes.
- If the message is issued for FASTMON, IMS does not call the FASTMON exit type and continues processing. This message is issued only once for the lifetime of the IMS system.
System programmer response
If this is a storage shortage, the region size of the address space might be too small. Increase the region size by changing the REGION= parameter on the IMS control region JCL and restart IMS.If the problem persists, save any memory dumps and IMS logs and contact IBM® Software Support. If no memory dumps were produced, create a console dump of the IMS control region.
